Subject [GitHub] spark pull request: [SPARK-8029] robust shuffle writer

    [SPARK-8029] robust shuffle writer

    Currently, all the shuffle writer will write to target path directly, the file could be
corrupted by other attempt of the same partition on the same executor. They should write to
temporary file then rename to target path, as what we do in output committer. In order to
make the rename atomic, the temporary file should be created in the same local directory (FileSystem).
    This PR is based on #9214 , thanks to @squito
